show magento scope switcher in admin grid edit form

Question

I'm working on a module in magento admin where I would like to show the scope selector as in manage products, manage categories, system configuration for my grid edit form.

![screenshot][1]

Can anyone help me how could I add that and store values in database specific to the scope selected?

Update
saveAction() from adminhtml controller

public function saveAction() {
    if ($data = $this->getRequest()->getPost()) {

        if (isset($_FILES['smalllogo']['name']) && $_FILES['smalllogo']['name'] != '') {

Add this to the layout handle for the add/edit page:

<reference name="left">
    <block type="adminhtml/store_switcher" name="store_switcher" before="-" />
    <!-- add other blocks if you have in here -->
</reference>

[EDIT]
If your models extend the EAV models you can save the values for a specific store by replacing

$model->setData($data)->setId($this->getRequest()->getParam('id'));

with

$storeId = $this->getRequest()->getParam('store', 0);
$model->setData($data)->setStoreId($storeId)->setId($this->getRequest()->getParam('id'));
